I would not recommend doing full face if you have tender or sensitive skin. It hurts, like bad, but I was told after a few regular sessions it gets better. My brows turned out great, but I left and quickly welts arose all over my face. I followed their instructions and washed my face as soon as I got home (6 -7 minuets later). Then, within the next 24 hours I have what looks like teenage acne. I did not do the aloe as they said that can some times cause breakouts. The teenage acne look is not what I was hoping for at Easter brunch. But my brows do look good, that is the reason for the two stars.
